MIAMI (AP) Miami Dolphins offensive coordinator Dowell Loggains is two weeks into a new job, and with his family back in Chicago he has been working late.

The head coach works later.

"When I leave the office every night, the only person left is Adam Gase," Loggains said Friday. "When you're sitting in your office at 10:30 at night in the offseason, trying to figure out corrections you need to make when the season didn't go the way you wanted it to, I have tremendous respect for that. Those are the type of people I want to be around."

The Dolphins announced the hiring of Loggains and other changes in the coaching staff as Gase begins the process of trying to rebound from a 6-10 season.

Three assistants changed titles. Shawn Jefferson will become assistant head coach/offense, Ben Johnson will become wide receivers coach, and Clyde Christensen will become director of football and player development.

Gase will continue to call plays. Loggains was the Bears' offensive coordinator the past two years, and he and Gase were on the Chicago staff together in 2015.

"We've had a really good working relationship," Loggains said. "We see football the same way - offensive football and quarterback play. So for me it was a no-brainer when I had a chance to come here and join up with him."

Loggains, 37, made the team at Arkansas as a quarterback even though he's 5-foot-6, and said he overcame any size disadvantage with his work ethic.

"It's the same way in coaching," he said. "You might not be the smartest guy. You've got to know your limitations and try to work harder than the next guy. That's how you stay in this league - try to outwork as many people as you can."
